"Switch to tab" using search

Tap the + (the plus sign) at the top right corner of the screen (bottom left corner on tablets in landscape mode) to open a new tab.

The new tab will load the Awesome Screen and a list of your Top Sites, Bookmarks and History. You can choose from these home screen options or type in a new search or URL.

View and reopen previously closed tabs
